Well, IMHO the Linux kernel is exceptional in many ways ...

Not only that.

First, each bug report has to reach the right lists/people and that's what we
can't assure using the Bugzilla alone right now.  To make the Bugzilla
generally useful for that we need to change the way in which the target of the
report is selected and make it send reports to mailing lists rather than to
individual people.

Second, once the bug report have reached the right place, we have two problems
to solve:
(1) we need to make the developers respond and actively work on the bug
(2) we need to make the tracking of the bug possibly unintrusive (ie.
    developers should be able to work with the reporter in a way that *they*
    prefer)
While it's generally difficult to solve (1), we can at least make (2) happen
(well, in theory).

Yet, the architecture choice affects the way in which the other choices are
made.  Also, the "sending to mailing lists" part is obviously missing.

No, it doesn't.  You can't send the initial report by email so that it's
registered by the Bugzilla, at least I'm not aware of such a possibility.

Also, if you "switch to email", and then want to switch back to the web
interface, the Cc list from the email messages will be lost.
